An Oakland officer who graduated from the police academy as class valedictorian last year was arrested Monday on suspicion of driving under the influence, officials said.

Officer Isaac Goins, 25, completed the 175th basic academy in January 2017 at the top of the 24-person class.

California Highway Patrol officers stopped Goins, who was seen drifting between lanes, at 2:20 a.m. Monday on eastbound Interstate 580 near the Park Boulevard exit in Oakland, said Officer Matt Hamer, a CHP spokesman.

He was booked four hours later at Glenn Dyer jail in Oakland, Hamer said.

“Any time a public servant, particularly a police officer, gets arrested it’s a disappointment to the city of Oakland,” Berton said. “Now we have to let the legal process play out.”

In the most recent police academy, the 177th, just 11 of the 33 recruits who began the program graduated. Kirkpatrick said at the time that some left on their own volition but others were dismissed for issues like a lack of maturity.
